Customer Reviews

Love the pants, miss the zippers (Review by Blake)

Great pants/shorts. Comfortable for day long activities. The only thing they are missing are zippers on the bottom of the pants for getting them off over my boots. Add zippers and this is a 5 Stars pair of pants.

Value and versatility (Review by lightweight and comfy)

I’ve had a pair of the Ferossi shorts now for a while and have loved them, so when I saw the Ferossis were available as convertible pants, I had to order a pair. I was not disappointed as they just extend the comfort range of the shorts, just zip the bottoms on when the mornings or evenings are cool. Two zippered back pockets and a zippered thigh pocket along with the regular front pockets are nice. I'm 6' and 175 lbs and the 32s fit well. The shorts come down to my kneecaps with the bottoms zipped off.

Excellent pants (Review by Ian)

These pants are true to size, light weight, and nice and breathable. The zip off legs make them very versatile. Pocket placement is good, and they are very comfortable. Highly recommended!
